I had complete engine failure on my 2021 115,000 mi Ford Explorer ST. The truck was only 3 years old. I heard a knocking noise and pulled over. Throughout the summer smoke had been coming out of the exhaust pipe every time I turned on the car before work. There was a cloud of smoke. A week before the engine failure I had the vehicle in the ford shop. They said everything was fine. I towed the vehicle to Currie Ford in Frankfort and they stated that there was catastrophic engine failure. Nothing could be done but I needed to put a new $12,000 engine in a $63,000 car. They said the warranty did not cover nor do I have any recourse. The safety of my family was placed at risk., I was travelling with my family, my wife, son, daughter, nephew who is [XXX] old and niece who is [XXX] . It left us stranded. There were no warnings. The dealership inspected the car a week before and said it was good to go. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
